Title: CFD Simulation for Wind Load on Octagonal Tall Buildings
Abstract: Lateral loads i.e. wind load, seismic load, govern the design of tall buildings. Wind code IS 875 (PART-3 rd ) provides the pressure coefficients (CP) only at 0o and 90o wind incidence angles and only for few standard cases.Therefore, experimental studies become important and wind tunnel experiment is carried out to measure wind loads on the models of tall buildings at different wind incident angles. CFD offers a very powerful alternative to predict the wind related phenomena on buildings or different kind of structures. A software package, FLUENT-14 (ANSYS 14.0) is used for CFD analysis. CFD analysis is carried out considering the same parameters as used in the experimental study.The buildings chosen in present study is octagonal in plan. Mean area weighted average wind pressures on the faces of the building models are measured in order to study the effect of varying wind incident angles namely 0o, 15o and 30o on wind pressure distribution.
